Blue Trains in Japan were long-distance sleeper trains, nicknamed as such for the color of the train cars. They consisted of 20-, 12-,583-, 14- or 24-series sleeper cars, and connected major destinations within Japan across long distances. For a time, other routes were served by a fleet of newer limited-express overnight trains, which were not blue.

The Sunrise Izumo is an overnight sleeping car train service in Japan operated jointly by Central Japan Railway Company and West Japan Railway Company since July 1998.
